The Red Grunt is like the Orange Grunt, except it has the ability to fire projectiles at the player. It is also noticeably slower than his orange counterparts.

A Red Grunt has 6 health but its projectiles make it more difficult to deal with than the Orange Grunt. The player can avoid the projectiles it fires by moving aside, jumping, or if the player has the Sword of Fortune they can reflect the projectiles away from them, possibly killing the Red Grunt.
